摘要： Systems are disclosed for providing a DC-bias network for a RF distributed amplifier. One embodiment may include a DC-bias network comprising a planar substrate having an input port configured to receive a DC input signal and provide a DC bias at an output port, a microstrip line mounted to the planar substrate and interconnecting the input port and the output port, and a plurality of RF resonators coupled to the microstrip line. Each of the plurality of RF resonators are configured to provide a substantially constant impedance for a respective portion of the frequency band of the RF signal

摘要： An LC filter structure and method for its fabrication, in which multiple shunt capacitors, multiple shunt inductors and multiple coupling inductors are printed on a metal layer formed on a thin dielectric substrate. The capacitors have first electrodes that are formed as spatially separated regions of the metal layer, and a common second electrode formed by a ground plane on the substrate. The shunt inductors are formed as spiral traces connected to the separated regions and to the ground plane, through conductive vias. The coupling inductors are similarly formed as spiral traces in the gaps between the separated regions, the ends of each coupling inductor being connected to respective adjacent regions of the metal layer.
